#831 SMPlayer freezes when screen is entirely black

[Nazar Mokrynskyi]

I'm observing this for quite a long time.
When I'm watching movies, occasionally when there is a transition between pieces and there is a few seconds of completely black screen occasionally everything freezes. If I wait for long enough (like minutes or half a minute if I press Alt+F4) I'm getting a message that SMPlayer encountered an error, and here is what I see in the text box of that window:

At the same time I see messages like following in dmesg:

I'm on Ubuntu 17.10 64-bit. GPU is Nvidia GTX 1080, driver version 384.59 (happened on previous drivers as well).
SMPlayer 17.7.0 (build 8599)
Qt 5.7.1 (compiled with Qt 5.7.1)
MPV 0.26.0

There are no issues with video games or other applications, only with SMPlayer, only when completely black screen for few seconds.
Let me know if you need any additional information.

[Nazar Mokrynskyi]

Freezed once on final titles, when there was a white text on mostly black screen. One more time freezed in windowed mode, when there was a white circle on otherwise black screen.

[Ricardo Villalba]

Is the problem still happening if you select a different video output (preferences -> general -> video) or if you turn off hardware decoding?

[Nazar Mokrynskyi]

Currently "Default" video output is used, but don't know how to check which exactly was selected. Will try opengl for now. Disabling hardware deconding would be unfortunate, but I'll try it next.

[Nazar Mokrynskyi]

opengl didn't help, going to disable hardware decoding

[Nazar Mokrynskyi]

No issues with hardware acceleration turned off
